LUBRICATING-PUMP.

SPECIFICATION forming part of Letters Patent No. 648,689, dated May 1,1900. Application filed March 9,1899. Serial No. 708,366. No mnlcl.i

To n.1] nfl/0711I imuy ormcfrn.:

llc it known that l, .louN li. MCCANNA, a resident ol' Chicago, in thecounty of Cook and State ol` Illinois, have invented certain new anduseful Improvements in Lubricatihg-Pumps,- of which the following isaspecification. y

My invention relates to certain new and useful improvements in what areknown as 1o lubricating-pumps, which are smallpumps ordinarily operatedfrom some reciprocating part of asteam-engine and employed to pump oilto any parts that it is desired tc have constantly and uniformlylubricated.

My invention is primarily concerned with a structure inlubricating-pumps whereby a single reservoir for the lubricatingmaterial may be employed in connection with two or more pumps which drawthe supply there- 2o from and which pumps may be operated from the samedriving mechanism.

My invention is further concerned with a novel structure and relation ofthe parts whereby the pump is removably secured in the oil-reservoir andoperated by a piston reciprocating through the side thereof, being astructure wherein the only parts that .ever become worn can readily beremoved and replaced.

3o My invention further relates to new and improved actuating mechanismfor use in such pumps,and includcs,amongother things, a novel clutchmechanism whereby the reciprocating rotary motion is applied to a shaftto give ,it an intermittent rotary motion.

Referring to -the sheets of drawings, in which the same letters ofreference are used to designate identical parts in all the views, Figure1 is a central section through va reser- 4o voir employing two pumps.Fig'. is a central sectional view of the indicating mechauism. Fig. 3 isa front elevation ol an indicating mechanism detached. Fig. 4 is`anelevation of the actuating mechanism with some of the parts broken awayto more clearly illustrate the details of the construction. liig. 5 is asectional View of the actuating mechanism on the line 5 5 of Fig. 4.Fig. 6 is a similar sectional view on the line 6 (3 of 5o Fi'g. -i.

dicating mechanism.

iu connection with the actuatingmechanism. Fig. S is a plan view withthe cap, indicating mechanism, and strainer removed. Fig. il is aninverted plan view ofthe actuating-slide, and Fig. 10 is a plan view ofthe base portion with the reservoir proper and the actuatingslideremoved and a portion of the casing broken away.

The reservoir A, which contains the oil or 6o other lubricatingmaterial, maybe of the c vlindrical shape shown, although any othershape might be employed. I have shown this reservoir A as secured by thescrews B or otherwise'on the hollow cylindrical base por- 65 The topofthe reservoir A has the rectangular aperture D therein, in whichaperture fits thecap E, which supports the iu- 'lhe aperture D is formedwith the flange F therein, and upon 7o this flange F rests the flange Gof the strainer Il, which, as shown, is of a shape to correspond withthe aperture D. The flange (l et the strainer H rests on the flange Fformed in the aperture, and the cap E, resting upon the upper side ofthe flange G and in the aperture D, serves to close the aperture andsecure the strainer in place. The cap E is l'ormed with the portion J,which serves as a 'bearing or casing for the indicating mechan- 8o ismproper. The lloatK is provided with the' stem L, which may be graduated,as shown in Fig. 3,'to indicate the amount of oil that has been pumpedout since the reservoir .was last filled. The scale on the stem L isgraduated to cooperate with the opening in the upper end of the portionJef the cap through which l it projects. It will be readily seen thatthe position ofthe float J will be regulated by the amount of oil in thereservoir and that con- 9o sequently the position of the stem L will in;dicate the amount ol' oil remaining'. To indicate the rate at which theoil is being pumped out, Iemploy the following constructien:

One side of the stem L is formed with the teeth N, which form a rack-barwhich meshes with the gear-pinion 0, which with the gearwheel P, towhich it is rigidly secured, is rotatably mounted upon the pin or shaft(3, roo passing through the aperture or recess formed in the portion Jof the cap. Journaled upon e esac-see the rate of which movement willindicate thel rate at which the oil is being pumped out of thereservoir. To protect the pointer U, I may place a glass plate X infront of it'and conveniently secure it in the cap W by means ot thespriugaing Y, fitting into a groove Z in the cap or cover W.

The pumping mechanism proper consists of the irregular-shapedportion orpiece A',

which has interiorly-screw-threaded openings in its bottom and top, andthe passage B', connecting them, which passage is enlarged at thebottom, as seen. The screw-threaded valve-seat C' is screwed into thebottom of the piece A', and the ball-valve D cooperates therewith, -aswill be readily apparent. The valve-seat formedby the upper end of thepassage B" is closed by theball-valve E. The connecting-piece F' isscrewed'into the 'upper end of the piece A' and has the aperture G'formed inv its lower side of a size to'accom` modate the movements ofthe valve E'. The

` pipe ll', which is screwed into its upper end,

serves to carry the oil to any desired place, and the holes J', boredthrough the central portion of this connecting-piece F', permit thepassage of the oil upward to the tube Il'.

This pieceA' has the preferably cylindricall portion K' projecting outthrough a similarlyshaped aperture Iin the side of the reservoir A, andthe nut L', coperating with the screwthreaded end of the cylindricalportion K', serves to hold this piece A' and its connected partsin'position. .Vhen itis desired to take the p'ump out for any purpose,it the cap E and strainer Il have been removed by lifting them out andthe nut L' taken oit the pipe H can be moved. toward the center of thereservoir, the slots M", leading to the aperture D, permitting ,thismovement. In the construction shown the cap E and the opening Dareelongated in the direction at right angies to the section in Fig. l, andby turning the pipe Il' so as to bring the longer portion of the part A'in line with the longer way of the opening it canv be withdrawn from thereservoir. Of course the reverse method is employed in assemblinhr theparts. The piston N' reciproeates in the bearing 0', formed in the pieceA',and through the stuliing-box P', which is closed bythe nut Q',screwed into the cylindrical end l' of the piece A'.

-To reciprocate the pistou N', the shaft S' is slowly rotated by meansto be subsequently described, and this'shaft S', which is mounted inbearings'forined in the base C of the ma passing through the shaft andinto the lug. As the shaft S rotates, the lug T' cooperates with theinterior bearing-surfaces of the downwardl y-proj ectin g lugs V', whichare earr'ied by the reciprocating slide W", 4which moves back and forthin the openings (see Fig. 10) formed in the sides of the base C. Arectangular aperture X' is out in the slide W' to permit the necessaryrotation of the camlug 'l". The ends of the slide `W' are turned upward,as shown in Fig. 1, and take into the apertures formed in the yokes Z',to be described. These pistons N' have the rectangular yokes Z' securedon their outer ends and into which the upturned'ends of the slide XV'project. In the outer ends of the yokes Z' are located the screws A2 andthe jam-nuts B2 thereon, by which the length of stroke of the pistons N'is regulated to discharge any amount of oil that may be desired. readilybe seen that if the screw A2 is in the position shown at the right handvof Figs. 1

and 8 the reciprocation of the slide YV' will not affect the pistou N',as the end of the slide W' will not contact with the yoke Z' to move itat all. If; however, the screw A2 is moved inward to a positioncorresponding to its position on the left-hand side of the malchine,after the slide l l' has moved to the thrown entirely out of operativeconnection with the slide \V', so that the operation of the pumps may becompletely regulated in every detail.

To rotate the shaft S', l employ the .following mechanism: Thevertieally-reciprocating rod C2 is supposed to be attached to anyreciprocating part of the engine, and this is secured in any desiredposition to 'the member D2, which is pivotally mounted upon theadjustable bearing E2, secured in any desired position upon the swingingrod F2, the inner end ot' which is furnished with a clamping split ,ringG2, by which it is secured upon the collar lle, projecting outwardlyfrom the circular plate J2. This collar ll`- may also extend inwardly,forming the collar K2, and the common aperture for these collars -formsa bearing by which the plate J2 is mounted upon the outer end of theshaft S', it being held in position by means ot the washer L2 and screwM2. Screwed upon or otherwise rigidly Secured to the shaft S' is thecollar N2 which chine, has secured thereon the lug T', which is shown asfastened thereto by the screw U',

It will curved dog T2, pivoted thereto.

each composed of the body portion S2 andthe The outer clutch member ispivotally secured in the outer cavity by means of the screw U2, passingthroughthe horizontal elongated slot. V2 in the face of the plate ordisk .Pand taking into the bearing stud or piutle W2, upon which theclutch member is pivotaliy mounted by means of the circular aperture X2.The enlarged aperture Y2, which is conveniently square, permits the freepassa-ge oi' the shaft and sleey@ K2. `Similarly it will be seen thatthe inner clutch member is secured in the innercavity by means of thescrew-bolt Z", passing through the horizontal slot Asin th'e flattenedface Q2 of the reservoir A and holding the bearing stud or pintle B3 inposition. The operation of these parts will be readily apparent. As thepart U2 reciprocat-es vertically, the arm F2 will he reci procated aboutthe center of the shaft S' as api vot and in its moveo ment willreciprocate the disk J2, to which it is secured. As the parts stand intheir normal position, as shown in Fig. 4C, the curved `flange T2 of theouter clutch member rests loosely against the inner side of the extendedperiphery P2 of the disk O2. As the arm F2 moves downward the tendencyof the pivotal point of the c uter clutch member to approach the side ofthe extended periphery against which its flange T2 takes, owing to theswinging of the pivotal point in a circle, causes the flange T2 to bindagainst the widened periphery P2 and the disk O2 to advance with theouter clutch member during its forward movement. As the arm F2is raisedthe clamping eiect of the clutch is removed and the disk O2 remainsstill, and consequently the shaft S', to which it is attached, remainsin its advanced position. The inner clutch member comes into playto-prevent an y possible friction between the disk J2 and the disk O2from carrying the disk O2 backward. The action of the clutch member inthis will be readily apparent, as if 'the widened periphery P2 of thedisk O2 were moved backward it immediately tends to clamp the innerclutch member and its fixed pivotal point absolutely preventsanybackward movement after it is once clamped.

As there is always a certain amount of gradual leakage out of thesmiling-box, I provide the slide W with the grooves C3 directly beneaththe ends of the stutlingbo \es,which carry this waste oil and dischargeit through the apertures D3 into the chamber formed in the base U of thepump. This oil is discharged upon the cam bearing-surfaces, and even ifit were not the oil which gradually accumulates in the chamber willeventually become deep enough so that the cud of the lug'l" lu itsrotation will take into the oil and carry enough with it to` thoroughlylubricate the bearing-surfaces with which it contacts. To draw oil anysurplus of oil that may accumulate in this chamber, I may provide thepipeES, opening into it, which is provided with the cock F8 for openingor closing it, as may be desired.

The complete operation ofthe pump will be readily apparent and nodetailed description thereof is deemed necessary. It will be seen thatthe amount of the feed can be easily and readily regulated by theadjustment of the bolts and nuts A2 and B2 and that the indicatorprovided will always show the actual amount being pumped out. Of courseit will be understood that vI might, if desired, employ only onel pumpin the reservoir, or I may employ more than two, conveniently, arrangingthem in pairs and providing a` slide W' for each pair, or I mightconnect a plurality of slides or form them integral.

It will be understood that I do not desire to be limited to the exactform shown and dcscribed, but that my invention may be embodied in avariety of forms, and that I do not desire to be limited therein, exceptas necessitated by the state of the art.
